Many people try to buy bitcoin regularly with a certain portion of their income because they can predict the potential of bitcoin. We generally prefer to use the DCA method as it encourages us to invest stress-free. I can collect bitcoins at my own interest. Anytime there may be a problem where I can't collect bitcoins for a specific period of time, I may be able to re-use the opportunity later. DCA does not mean that I have to collect bitcoins compulsorily. However, for regular Bitcoin purchases, adopting this effective method would be significant for accumulating bitcoin or increasing bitcoin portfolio.
I agree from a strategic perspective, it's definitely good. Maintaining consistency and regularly buying bitcoins is not mandatory, but if you are able to do it then you will definitely have more bitcoins in your bag. It doesn't matter how you do it, as long as you can balance your expenses and budget the rest, then you're free to invest.
It will turn into a must if you really have good intentions and seriousness in the accumulation that you want to run, anyone always wants bitcoin and the only way for you to be able to get or increase the amount of bitcoin then obviously you need to maintain the following planning as well as the consistency of the allocation of money on your bitcoin accumulation. On the other hand, yes I understand that not everyone is able to do it because there are quite a lot of factors that can make you experience delays and one of them is like what you said where finances are always a problem for most people who end up experiencing delays.
Although investing is basically a choice but not everyone can choose to do it and as I said above that they really need to change something in their finances one of which is by adding a part-time job to increase income, although investing can be very profitable when you succeed but it is not the right decision if you basically prioritize investing over budgeting to meet daily needs because after all your life is more important, and one way if you really want to get involved is obviously by improving financial strength, if everything already looks balanced in the sense that you don't have a problem even if you share some of your money on other things like bitcoin then obviously you can start getting more serious in accumulation.
Sometimes many people fail to invest in bitcoin not necessarily that they don't have money to invest. Or that they need extra income to income to boost their investment chances. Some of these people are just looking for someone to act as a motivating factor for them before they can invest. Many people in here develop more interest in investing and hodling bitcoin because of their continuous visiting and reading of this thread, and seeing the knowledge that are being shared here and it motivated them. There could be several reasons why many hesitate to invest, but like you said above, investment is basically a choice.
